LOVELY HIJAB: Vintage Hat Pins

I came across these in my wanderings around London city and found these beauties in a bespoke jewellery and clothes shop in Greenwich. They are apparently antiques (well some of them anyway) and were originally hat pins, although the shop-owner said there were many hijabis who had expressed an interest in them. They look truly beautiful together, but a bit too big for me I think! But very tempting, am still considering going back there to buy a few!
